Hybrid Blockchain Framework for Secure and Scalable Internet of Things (IoT) Networks (HB-IoT): A Novel Approach

The growing dependence on IoT devices for critical applications has intensified security concerns, particularly in the areas of data integrity, privacy, and scalability. Traditional blockchain technologies, while effective in certain contexts, often fall short in addressing the unique needs of IoT networks, such as the demand for high transaction throughput and minimal latency. This paper introduces the Hybrid Blockchain Framework for Secure and Scalable IoT Networks (HB-IoT), a cutting-edge model that combines the advantages of both permissioned and permissionless blockchains to enhance security and scalability in IoT ecosystems. The HB-IoT framework incorporates a multi-layered consensus mechanism designed to efficiently process large volumes of transactions while ensuring robust security. Our qualitative and quantitative analyses show that HB-IoT outperforms current blockchain solutions in terms of transaction speed, energy efficiency, and resilience against common cyber threats. Additionally, we explore HB-IoT's potential to enable secure data exchange, decentralized identity management, and trustless collaboration within IoT networks.
